NON-REFILLABLE BOTTLE.

Specification of Letters Patent. Patqantedl U01). 2396, 1915.

Application filed November 26, 1913. Serial No. 803,136.

To all whom it may concern.

Be it known that VViILIAM F. THO PSON, deceased, who in his lifetime wasa citizen of the United States, and a resident of the city of New York,in the county and State of New York, did invent certain new and usefulImprovements in Non-Refillable Bottles, of which the following is aspecificatio This invention relates to non-refillable bottles.

It seeks to provide an eificient and reliable device and one which canbe manufactured and assembled at a reasonable cost.

Heretofore, various designs of non-refillable bottles have been proposedbut they have nearly all been impracticable because their structureswere of such nature as to involve an excessive cost in the manufacture.Many of them have been unable to successfully resist attempts to refillthe bottle.

In the present invention the structure is not only capable ofefficiently resisting efforts to refill the bottle, but the structure isso designed that it is capable of being manufactured and assembled at acomparatively small cost.

In the drawings forming part. of this specification, Figure l -is asectional elevation of the upper portion of a bottle to which theinvention is applied, the bottle being in upright position. Fig. 2 is asimilar view showing the bottle tilted and the cork removed for outflowof the liquid. Fig. 3 is a side elevation. of the valve case removed.Fig. 4c is a plan view of the cap for the upper end of the valve case.Figs. 5, 6 and 7 are sectional plan views taken on the lines 5-5, 6-6,and 77, respectively, of Fig.- 1.

Referring now to the structure shown in the drawings, 1 is the body ofthe bottle having the lower'portion 2 of its neck made integral with thebody and'the upper por-. tion 3 made in a separate piece and united,

with the part 2 by a thin metal sleeve 4 and a thin layer of cork 5. Thetwo parts of the neck are formed with annular re cesses 6 into which thesleeve 4: is pressed, the parts of the neck being joined together afterthe bottle has been filled and the valve device has been. insertedwithin theneck portion 2.

The invention resides in the construction and arrangement of the valvedevice which consists of the valve case and valve. The valve case is atubular casting of glass or other fictile material, being open from endto end. The upper portion 7 has a solid imperforate side wall andthelower portion 8 is in the form of a ring. The intermediate portion ofthe valve case is in the form of separated rings 9 which are unitedtogether and with the upper and lower portions 7 and 8 by fourlongitudinal ribs 10. The valve case is of less diameter than theinternal diameter of the neck so as toleave between the two a flow spacefor the liquid, and tapers slightly from its upper to its lower end. Itis suitably supported within the neck so as to be readily adjustedtherein. For this purpose, the neck of the bottle preferably has acontracted portion- 11 at its base which provides the support for thecase, no open space being permitted between the base of the neck and thepart 8 of the case, so that the liquid is compelled to fiow out throughthe bore of the part 8. This part 8 is provided with a flange l2 andimmediately beneath it and surrounding the part 8 is a ring of packingor gasket 13, preferably of cork. The upper end of the case is closed bya removable glass cap 14. Before the cap is put in place the valve 15,made of glass or other fictile material and in the form of asolidpiston, is inserted with in the case. The cap is provided with acentral projection 16 surrounded by a ring of packing or gasket 17preferably made of cork, which fits within the upper end of the isformed directly in the part 8 of the valve case itself and, in thepreferred arrangement, the valve seat istubular and tapering and thehead 20 of the valve is cylindrical and tapering. The valve seat, beingformed directly in the case itself, may be, readily ground to accuratelyfit the valve head. It

7 is important from an economical standpoint that the valve seat beformed in the valvecase itself rather than in the neck of the bottlebecause the case can be very accurately cast and ground, Whereas, itwould be difiicult and expensive to form a suitable valve seat in theneck of the bottle. The valve being made of solid glass, is of suitableweight to readily open and close by gravity. The upper end of thevalveis provided with a narrow bead 21 which closely fits the bore islocated Within the case between the cap I 14 and the upper end of thevalve. The upperpart 7 of the case is provided on its exterior withtwo-opposite transverse projections 23 and 24: and beneath theseprojections'23 and 24 are two similar opposite -projeetions'25 and26,the upper and lower projectionsbeing placed in staggered ar-,

rangement with reference to each other.

These projections are provided to prevent the access-of a wire or otherinstrument to the valve should any attempt be made to 1 insert such aninstrument between thencase and the neck, to-hold the valve open whenthe bottle is in upright position with the intent to; surreptitiouslyrefill the bottle.

7 The bottle is provided with the usual sealing cork 27. a

In using the invention the sealing cork 27 is first extracted and thebottle may then be canted to pour out 5 its contents. When thuslycanted, the valve 15 moves from its seat'by its own weight and theliquid flows out freely around the valve, thence through the aperturesbetweenthe rings 9 of the valve case, thence along the neck of thebottle and outside of the. valve case and finally throughthe spacesbetween the radial projections 18 of the cap. Whenthe'valve moves backfrom its seat the bead QI-slides' on the inner surface of the part7 ofthe valve case and keeps the upper end and stem of the valve centered inthe valve case so that the liquid may fiowaround the valve stem and outbetween; all the rings of the valve case.

The flow of the liquid is indicated in Fig. 20f the drawings;

-What I claimis V 1. In a non-refillable bottle, the combination withthe neck having contracted portions near its upper and lower ends; of atubular valve case within and partially filling the neck, said valvecase having an upper imperforate portion, an intermediate conical headand an elongated stem of less diameter than the internal diameter of theintermediate and upper portions of the valve case to permit outflow ofliquid above the valve head when the valve is in open position; a coiledspring within the valve case and above the valve to assist the latter toits seat, said spring and valve being so proportioned that the springcloses the valve when the bottle is in horizontal position and the valveby its own weight opens against the spring when the bottle istiltedslightly below horizontal position; a removable cap to close theupper end of the valve case and held in place by the upper contractedportion of the neck,-saidneck being madein two parts permanently unitedby an external sleeve to permit the insertion of the valve case and cap.

2.- In a non-refillable bottle, the combination with the neck havingcontracted portions near its upper and lower ends; of a tubular valvecase within and partially filling the neck, said valve case having anupper imperforate portion, an intermediate perforate portion and a lowerimperforate portion and supported by the lower contracted portion of theneck; a conical valve seat in said lower portion of the valve case; avalve within the case, said valve having a conical head and an elongatedstem of less diameter than the internal diameter of the intermediate andupper portions of the valve case to permit outflow of liquid above thevalve head when the valve is in open position; a coiled spring withinthe valve case and above the valve to assist the latter to its seat,said spring and valve being so proportioned that the spring closes thevalve when the bottle is in horizontal position and the valve by its ownWeight opens against the spring when the bottle is tilted slightly belowhorizontal position; a removable cap to close the upper end of the valvecase and held in place by the upper contracted portion of the neck, saidneck being made in two parts/permanently united by an external sleevetopermit the insertion of the valve case and cap, said valve case andvalve each being made of fictile material and cast in one piece.
